The injection filling process of LFC with different position of bead inlets was simulated by the DEM model

in which the Euler-Lagrange divorced particle model was established.Flow kinetic characteristics of densified gas-solid phase of foamed beads during filling process was investigated by the numerical simulation.The movement of foamed beads is closely related with gas-phase pressure distribution.The inner-outer pressure difference formed near venting plug during filling process drives the bead movement.At fixed other conditions

injection filling process of foamed beads was simulated with different positions of bead inlets.The results reveal that the bead inlets should be set at a wider location of cavity to reduce the hinder near beads inlets and movement direction of beads as possible to realize the smooth flow.
